New study from Houston research team looks at how the Earth cycles fossil carbon

Carbon cycles through Earth, its inhabitants, and its atmosphere on a regular basis, but not much research has been done on that process and qualifying it — until now.

In a recent study of a river system extending from the Peruvian Andes to the Amazon floodplains, Rice University’s Mark Torres and collaborators from five institutions proved that that high rates of carbon breakdown persist from mountaintop to floodplain.

“The purpose of this research was to quantify the rate at which Earth naturally releases carbon dioxide into the atmosphere and find out whether this process varies across different geographic locations,” Torres says in a news release.

Torres published his findings in a study published in PNAS, explaining how they used rhenium — a silvery-gray, heavy transition metal — as a proxy for carbon. The research into the Earth’s natural, pre-anthropogenic carbon cycle stands to benefit humanity by providing valuable insight to current climate challenges.

“This research used a newly-developed technique pioneered by Robert Hilton and Mathieu Dellinger that relies on a trace element — rhenium — that’s incorporated in fossil organic matter,” Torres says. “As plankton die and sink to the bottom of the ocean, that dead carbon becomes chemically reactive in a way that adds rhenium to it.”

The research was done in the Rio Madre de Dios basin and supported by funding from a European Research Council Starting Grant, the European Union COFUND/Durham Junior Research Fellowship, and the National Science Foundation.

“I’m very excited about this tool,” Torres said. “Rice students have deployed this same method in our lab here, so now we can make this kind of measurement and apply it at other sites. In fact, as part of current research funded by the National Science Foundation, we are applying this technique in Southern California to learn how tectonics and climate influence the breakdown of fossil carbon.”

Torres also received a three-year grant from the Department of Energy to study soil for carbon storage earlier this year.

Houston-based CO2 utilization company HYCO1 has signed a memorandum of understanding with Malaysia LNG Sdn. Bhd., a subsidiary of Petronas, for a carbon capture project in Malaysia, which includes potential utilization and conversion of 1 million tons of carbon dioxide per year.

The project will be located in Bintulu in Sarawak, Malaysia, where Malaysia LNG is based, according to a news release. Malaysia LNG will supply HYCO1 with an initial 1 million tons per year of raw CO2 for 20 years starting no later than 2030. The CCU plant is expected to be completed by 2029.

"This is very exciting for all stakeholders, including HYCO1, MLNG, and Petronas, and will benefit all Malaysians," HYCO1 CEO Gregory Carr said in the release. "We approached Petronas and MLNG in the hopes of helping them solve their decarbonization needs, and we feel honored to collaborate with MLNG to meet their Net Zero Carbon Emissions by 2050.”

The project will convert CO2 into industrial-grade syngas (a versatile mixture of carbon monoxide and hydrogen) using HYCO1’s proprietary CUBE Technology. According to the company, its CUBE technology converts nearly 100 percent of CO2 feed at commercial scale.

“Our revolutionary process and catalyst are game changers in decarbonization because not only do we prevent CO2 from being emitted into the atmosphere, but we transform it into highly valuable and usable downstream products,” Carr added in the release.

As part of the MoU, the companies will conduct a feasibility study evaluating design alternatives to produce low-carbon syngas.

The companies say the project is expected to “become one of the largest CO2 utilization projects in history.”

HYCO1 also recently announced that it is providing syngas technology to UBE Corp.'s new EV electrolyte plant in New Orleans. Read more here.
